Sure V might have said that after splitting and regaining his humanity he started to regret his choices and now he's trying to "fix some of them" (Urizen problem), but in the end he chooses to merge with him just to defeat his older brother.

That was his plan all along. Dante stated it. In the end it seems like V was playing the whole time just to merge with Urizen. Even his servants knew that it was V's goal all along.
